Do you think it could be fake - i.e. a bunch of bots trading back and forth to generate interest? If so, that's a very clever way of bootstrapping to critical-mass popularity. That reminds me of a story of a new york nightclub that pretended to be jam packed the first few nights with a bouncer outside telling everyone: "sorry, the place is full", when in fact, the place was empty. Needless to say, the first night it was actually open, hundreds were standing in line.

The /r/dogecoin subreddit has some _very_ active "tipbots." Many threads consist of people tipping each other back and forth. It's almost like a Potlatch. It's pretty ridiculous and fun and it's one of the reasons adoption among redditors has taken off.

Dogetipbot's creators say it's only exchanging about $1500 USD/day of DOGE, so that doesn't explain it.
